Jim,
Version 2, which I've been running for the last 2+ years, actually uses 4" diameter racing brake duct (high temperature) that runs down to a vacuum formed inlet (used a lot for inlets to brake cooling systems). Stay tuned on the plenum front - YT is going to work up something based on a conversation the two of us had. I'm also working on yet another approach that will be a little more involved... 
-Bill (once an engineer, always an engineer....  )
p.s. on the TB front, OT and I are already running intakes that are ported/polished to match the TB. OT also did some minor mods to the TB to provide for a totally horizontal positioning of the plates at WOT
